PDT rebuild error: `SQL Error in CREATE TABLE as SELECT: This connection has been closed`


Userlevel 2

This is likely a timeout error.

If the PDT is persisted with the persist_for parameter then this PDT can only be built by querying it via an explore/look/dashboard and the build is subject to Looker's 60 minute proxy timeout.

If you have determined that this PDT is timing out due to Looker's proxy timeout, consider persisting using a sql_trigger_value instead. PDTs persisted with a sql_trigger_value are generally built by the regenerator and are not affected by Looker's 60 minute proxy timeout.
